Control valve fugitive emissions
- Exxon Research and Engineering Co., Florham Park, NJ (United States)
Tighter limits on air pollutant releases are not only an environmental issue, but a maintenance challenge. Fugitive emissions, also known as equipment leaks, are sourced from valves, connectors/flanges, pump and compressor seals, pressure relief valves and other piping-system components, located throughout any process plant. Although these emissions are sometimes visually detected, often they are found with sensitive gas detection instruments placed adjacent to the leak point. With the implementation of new Reasonably Available Control Technology (RACT) and Maximum Achievable Control Technology (MACT) requirements for VOCs and air toxics, minimizing fugitive emissions from valves has become a major focus for environmental and maintenance personnel. To ensure that the most efficient control method is applied, maintenance and process engineers must identify design, operating and maintenance factors that have the greatest impact on reducing the frequency and magnitude of component leaks. Listed guidelines highlight how to more cost-effectively mitigate air-pollutant emissions from valves. Cost is an important factor when considering the project scope.
